A preparation of fowl antibody to the 2,4-dinitrophenyl group (DNP), made from antisera to DNP-bovine γ-globulin by dissociation of a specific precipitate, was more than 90 per cent precipitable by DNP-ovalbumin. This antibody with an approximate molecular weight of 165,000 and the immunoelectrophoretic properties of γG-globulin, precipitated with antigen only in 8 per cent NaCl. It fixed fowl complement, but did not agglutinate tanned fowl red cells coated with DNP-protein. It had no skin sensitizing activity. Its amino acid composition was significantly different from that of mammalian antibodies. Some of the properties of another DNP-specific antibody that appeared later in immunization are also described.
一种由针对二硝基苯基(DNP)的鸡抗体制成的制剂,该抗体是通过解离特异性沉淀物从抗DNP - 牛γ球蛋白抗血清制备而来,它可被DNP - 卵清蛋白沉淀的比例超过90%。这种抗体的分子量约为165,000,具有γG - 球蛋白的免疫电泳特性,仅在8%氯化钠中与抗原沉淀。它能固定鸡补体,但不能凝集包被有DNP - 蛋白的鞣酸处理鸡红细胞。它没有皮肤致敏活性。其氨基酸组成与哺乳动物抗体有显著差异。文中还描述了免疫过程后期出现的另一种DNP特异性抗体的一些特性。
